Abstract
The utility model relates to a power cable and especially relates to a wire-armored power cable. A reinforced type wire-armored environment-friendly power cable comprises second type annealed copper conductors. Core wires are formed by coating a modified environment-friendly polrvinyl chloride insulation layer respectively on the outer sides of a plurality of conductors. A warping tape and a modified environment-friendly polrvinyl chloride inner sheath are sequentially arranged on the outer sides of the three strands of core wires. Fillers are also filled between the warping tape and the core wires. A wire-armored layer and an outer sheath are further arranged on the outer side of the inner sheath. The outer sheath is divided into an inner layer and an outer layer. A nylon braiding reinforcing layer is arranged between the inner layer and the outer layer of the outer sheath. The mechanical strength of the cable sheaths is significantly enhanced. The cable provided in the utility model will not suffer deformation problems during laying and running processes.
Description
Technical field
The utility model relates to power cable, relates in particular to a kind of steel wire armored power cable.
Background technology
The tradition steel wire armored cable in the laying installation process or the distortion of the cable problem that often occurs in service, sometimes even the oversheath phenomenon of bursting apart occurs, thereby causes safety problem.In order to prevent the cable cover(ing) cracking, the general employing increases thickness of cable sheath, so makes cable weight increase the bending property variation.
Summary of the invention
The utility model is intended to address the aforementioned drawbacks, and a kind of reinforced steel wire armouring environmental-friendly power cable is provided.The mechanical strength of cable cover(ing) that the utility model is greatly high makes cable problem on deformation can not occur laying with in service.
For addressing the above problem, a kind of reinforced steel wire armouring environmental-friendly power cable, it comprises two class annealed copper conductors, some conductor peripheral hardware modified environment-friendly polyvinyl chloride insulation layers consist of heart yearn, three strands of heart yearns are followed successively by twining package tape and modified environment-friendly polyvinyl chloride inner sheath outward and are provided with filler, inner sheath is provided with wire armoring and oversheath outward, described oversheath is divided into inside and outside two-layer, is provided with the knit nylon reinforced layer between the inside and outside two-layer oversheath.
The utility model is optimized cable cover(ing), adopt two jacket structures, add one deck nylon yarn braiding structure in the two-layer sheath, the so greatly high mechanical strength of cable cover(ing) under the prerequisite that does not increase cable jacket thickness makes cable problem on deformation can not occur laying with in service.Compare with traditional armoured power cable, the utlity model has following advantage:
(1) mechanical strength, tensile strength, compressive strength rate tradition steel wire armored cable exceed 10% ~ 30%.
(2) cable is laying, problem on deformation can not occur in the running.
(3) less than traditional cable weight, saved cable cost, offer convenience for transportation, construction.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1 is the utility model schematic diagram.
Embodiment
As shown in Figure 1, a kind of reinforced steel wire armouring environmental-friendly power cable, it comprises two class annealed copper conductors 1, some conductor peripheral hardware modified environment-friendly polyvinyl chloride insulation layers 2 consist of heart yearn, three strands of heart yearns are followed successively by twining package tape 4 and modified environment-friendly polyvinyl chloride inner sheath 5 outward and are provided with filler 3, inner sheath 5 outer wire armoring 6 and the oversheaths of being provided with, described oversheath is divided into inside and outside two-layer, is provided with knit nylon reinforced layer 8 between the inside and outside two-layer oversheath 71,72.
